Hi, I went to RHUL for Biochemistry (so many of my modules were overlapping with Biomedical Sciences all 3 years).
I personally loved it there and am so glad I cleared into RHUL as opposed to my first choice because it was a campus university and I had a great experience.
The teaching quality in the department of biosciences is pretty good in my opinion, you can always email or go to the lecturers when you need them and they hold revision sessions towards exam season. My lecturers even let me borrow their own textbooks when the library had run out during exam season.
There's tutorial every month or so where your tutor will set you work that is based on upcoming work you might have to do e.g. if you have to do a project presentation, your tutorial work will be to practice that and present it in your tutor group to receive feedback.
In terms of university, I think it's a good university, top 30 (at the moment 23 on Complete University Guide which is above a lot of Russell Group universities).
Most of the halls are quite modern and if you're fortunate enough to live in Founders Hall, it's absolutely beautiful and you can roll out of bed in your pajamas if you have a lecture in the Main Hall (which is in the Founders building).
Affordability, it's part of the University of London but slightly cheaper than London and there's so many opportunities on campus for part-time jobs e.g. student ambassador, library assistant, resident advisor which are all above minimum wage and I had 3 part-time jobs supplementing my income and it didn't add to my workload or stress. The student union shop isn't terribly priced, there's also a fresh food market by the students union and an asian market. We also have days when there's hot food stalls outside there and it's unreasonably priced. Event nights also do some cheap drinks or deals like 2 for 1.
I enjoyed RHUL far more than going to one of the top 5 UK universities for my master's.
